<p>PROBLEM TO BE SOLVED: To obtain an indoor unit of an air conditioner capable of preventing dripping of condensate water to the outside of the machine even when refrigerant superheating degrees at an indoor heat exchanger outlet becomes large during a cooling operation.SOLUTION: An indoor unit of an air conditioner includes an indoor heat exchanger 13 configured by including: a plurality of fins 20 arrayed at intervals; and heat exchangers 13AU, 13AL, 13B having a plurality of heat transfer pipes 21 which are inserted in the plurality of fins 20, are provided in a plurality of stages in a stage direction that is a direction orthogonal to the airflow direction, and are provided in a plurality of rows in a row direction that is the airflow direction. Each of the heat exchangers 13AU, 13AL, 13B is arranged so as to be inclined with respect to the gravity direction. Out of the plurality of rows, at the heat transfer pipe 21 at the lowest stage side in the gravity direction lowest rows L1, L2, L3, a refrigerant inlet is arranged in the case where the indoor heat exchanger 13 functions as an evaporator, and a refrigerant passage is configured so that the refrigerant flowed in from the refrigerant inlet flows to the upper stage side heat transfer pipe 21 from the lower stage side in the gravity direction lowest row.</p> |
